Rose plant Jacmiss

ABSTRACT

A miniature class rose plant having compact spreading growth habit, high, nearly constant production of flowers, attractive light pink flower color, and disease resistant glossy foliage.

The present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by me by crossing the variety Over the Rainbow, with the variety Lavender Lace.

The primary objective of this breeding was to produce a new rose variety having the vigor and flower production of the female parent, Over the Rainbow, coupled with the dwarf habit and glossy small foliage of the male parent, Lavender Lace. The objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents as well as from all other varieties of which I am aware:

1. Compact spreading habit.

2. High, nearly constant production of flowers.

3. Attractive light pink flower color.

4. Disease resistant glossy foliage.

Asexual reproduction of this new variety by budding, as performed at Somis, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color terminology in accordance with the Royal Horticultural Society (London) Colour Chart, except where ordinary dictionary significance of color is indicated.

Parentage:

Seed parent.--Over the Rainbow.

Pollen parent.--Lavender Lace.

Petalage.--Number of petals under normal conditions: 50 to 60.

Color.--The upper side of the petals is Red Group 49C to D fading to White Group 155D at flower edges. The reverse side of the petals is White Group 155D. The base of petals has a small greenish white half moon at the point of attachment. The major color on the upper side is Red Group 49D.

Variegations.--None.

Discoloration.--No general tonality change at the end of the first day. At the end of the third day, gradual fading to White Group 155D.

Fragrance.--Slight.

Petals:

Texture.--Thin.

Shape.--Deltoid.

Form.--Tips slightly recurved, edges slightly quilled.

Arrangement.--Imbricated, with many petaloids in the center.

Persistence.--Petals drop off clearly before drying.

Lastingness.--On the plant: Fair, about 3 to 5 days. As a cut flower: Fair, about 3 to 5 days.

Reproductive parts:

Anthers.--Size: Medium. Quantity: Many. Color: Reddish brown. Arrangement: Regular around styles, mixed with petaloids.

Filaments.--Color: White.

Pollen.--Color: Gold yellow.

Styles.--Color: Red.

Stigmas.--Color: Red.

Plant form: Bush.

Plant growth: Vigorous, dwarf, compact, spreading. The plant grows as wide as it does tall (about 18 inches×18 inches).

Foliage: Number of leaflets on normal mid-stem leaves: 5.

Size.--Small, about 2 to 21/2 inches in length.

Quantity.--Normal.

Color.--New foliage: Reddish. Old foliage: Medium green.

Leaflets:

Shape.--Pointed oval.

Texture.--Upper side: Glossy, smooth.

Edge.--Serrated.

Serration.--Single, small.

Petiole rachis.--Color: Reddish.

Petiole underside.--Smooth.

Stipules.--Long, bearded.

Disease resistance.--Resistant to powdery mildew under normal growing conditions at Somis, Calif. The variety is also resistant to rust in Somis, but susceptible to blackspot.

Wood:

New wood.--Color: Reddish. Bark: Smooth.

Old wood.--Color: Green.

Prickles:

Quantity.--Ordinary quantity on main canes from base and on laterals from main canes.

Form.--Straight to slightly hooked downward.

Color when young.--Red.

Small prickles:

Quantity.--None on main stalks and laterals. 

I claim:
 1. A new and distinct variety of rose plant of the miniature class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its distinctive compact spreading habit of growth, disease resistant glossy foliage, attractive flower form and light pink color, and its high, nearly constant production of flowers.
